Protect the Source

By protecting the source of our drinking water, we reduce the chance of illness and keep water supply treatment costs low. IVGID Public Works is a member of the Tahoe Water Suppliers Association (TWSA), a Lake Tahoe based partnership comprised of California and Nevada municipal water agencies which are dedicated to providing clean and safe drinking water. Our water source is Lake Tahoe and is considered some of the finest drinking water in the world. Everyone can help protect the quality of our drinking water through simple sanitary practices.

Do your part to keep Lake Tahoe clean:

Do not dump portable toilets or holding tanks in or near the lake

See a spill or boat sink, call you local Sheriff’s Department

Always use the restroom facilities, not the lake and keep diapers out of the water

Do not swim if you are sick or just recovering from illness

Pick up after your dogs

Dog Waste: What is the real scoop on dog poop?

Dog poop is not just an aesthetic issue, but a water quality issue. People have become concerned about the effects of accumulated dog waste on water quality, especially in Lake Tahoe. Dog waste, like any waste, may contain a variety of microbes which could cause diseases that can potentially be transmitted to humans through our water. A recent study conducted by scientists at University of Nevada Reno Cooperative Extension sheds light on the risks of water contamination from dog feces, especially during the colder months.

Invasive Species: Asian Clam/Quagga Mussels

Spreading invasive species in Lake Tahoe like Quagga Mussels, Zebra Mussels and New Zealand Mud Snails violates local, state, and federal laws and affects our water quality. Help us prevent these issues by learning about them, properly preparing your boat, and following inspection laws. Visit TahoeBoatInspections.com and TahoeKeepers.org for more information.

Fertilizers

Phosphorus is one of the three key pollutants reducing Lake Tahoe’s clarity. Applying too much water, fertilizer, and pesticides on your lawns directly impacts Tahoe’s water quality and fuels algae growth. The Tahoe Regional Planning Agency (TRPA) recommends the use of phosphorus-free fertilizer. Read more about this issue and how to choose your fertilizer on the TRPA website.
